Answer 1

Ответ:

$1) \frac{6}{5} -\frac{3}{1} =\frac{6-15}{5} =-\frac{9}{5}$

$2) \frac{3}{1} -\frac{6}{5} =\frac{15-6}{5} =\frac{9}{5}$

$3) \frac{2}{1} -\frac{3}{2} =\frac{4-2}{2} =\frac{1}{2}$

$4) \frac{3}{2} -\frac{2}{1} =\frac{3-4}{2} =-\frac{1}{2}$

$5) \frac{3}{1} -\frac{7}{1} =-\frac{4}{1}$

$6) \frac{7}{3} -\frac{3}{1} =\frac{7-9}{3} =-\frac{2}{3}$

$7) \frac{6}{5} -\frac{8}{5} =-\frac{2}{5}$

$8) \frac{8}{1} -\frac{3}{1} =\frac{5}{1}$
